Silly idea. It's because he's in no position to legitimate spending money on an extravagant parade. The present mayor of Nagoya is famously demanding a permanent 10% cut on municipal taxation which many on the city council board oppose. Many see this as nice in principle but undoable in the long run given Japan's aging and shrinking population and new measures introduced to give financial aid to families with children.

So he initially said to the media that he was going to plan a huge parade, and he still probably wants to do it, but then realized he couldn't get the city council to agree to budget it without them questioning his 10% tax cut policy.

Mao and all the other skaters should just tell the mayor to stuff it for unwittingly involving her in municipal politics.
